+/* minidump_format.h: A cross-platform reimplementation of minidump-related
+ * portions of DbgHelp.h from the Windows Platform SDK.
+ *
+ * (This is C99 source, please don't corrupt it with C++.)
+ *
+ * This file contains the necessary definitions to read minidump files
+ * produced on ppc64. These files may be read on any platform provided
+ * that the alignments of these structures on the processing system are
+ * identical to the alignments of these structures on the producing system.
+ * For this reason, precise-sized types are used. The structures defined
+ * by this file have been laid out to minimize alignment problems by ensuring
+ * ensuring that all members are aligned on their natural boundaries. In
+ * In some cases, tail-padding may be significant when different ABIs specify
+ * different tail-padding behaviors. To avoid problems when reading or
+ * writing affected structures, MD_*_SIZE macros are provided where needed,
+ * containing the useful size of the structures without padding.
+ *
+ * Structures that are defined by Microsoft to contain a zero-length array
+ * are instead defined here to contain an array with one element, as
+ * zero-length arrays are forbidden by standard C and C++. In these cases,
+ * *_minsize constants are provided to be used in place of sizeof. For a
+ * cleaner interface to these sizes when using C++, see minidump_size.h.
+ *
+ * These structures are also sufficient to populate minidump files.
+ *
+ * These definitions may be extended to support handling minidump files
+ * for other CPUs and other operating systems.
+ *
+ * Because precise data type sizes are crucial for this implementation to
+ * function properly and portably in terms of interoperability with minidumps
+ * produced by DbgHelp on Windows, a set of primitive types with known sizes
+ * are used as the basis of each structure defined by this file. DbgHelp
+ * on Windows is assumed to be the reference implementation; this file
+ * seeks to provide a cross-platform compatible implementation. To avoid
+ * collisions with the types and values defined and used by DbgHelp in the
+ * event that this implementation is used on Windows, each type and value
+ * defined here is given a new name, beginning with "MD". Names of the
+ * equivalent types and values in the Windows Platform SDK are given in
+ * comments.
